吡唑烷-3,5-二酮和苯并恶唑分别通过 NN 键形成和 C,O 键的电化学合成代表了一种容易获得医学相关结构的方法。电化学作为一项关键技术确保了安全和可持续的方法。通过将循环伏安法和合成研究相结合,我们深入了解了这些反应的机制。研究了苯胺和二苯胺的电子转移行为并得出以下结论:NN 键的形成涉及作为中间体的双自由基,而苯并恶唑的形成基于阳离子机制。除了这些研究之外,我们还开发了一种合成路线,以混合二苯胺作为 NN 偶联的起始材料。

The CuCl catalyzed direct trifluoromethylation of sp2 C–H bonds has been realized, using the Togni reagent as the CF3 source. This reaction achieves the goal of regio-selectively converting C–H into C–CF3 with ecological and readily available starting materials.
Compounds are provided that act as potent antagonists of the CCR9 receptor, and which have been further confirmed in animal testing for inflammation, one of the hallmark disease states for CCR9. The compounds are generally aryl sulfonamide derivatives and are useful in pharmaceutical compositions, methods for the treatment of CCR9-mediated diseases, and as controls in assays for the identification of CCR9 antagonists.
